Informationen zum Autor Ethirajan Rathakrishnan , Indian Institute of Technology, India Klappentext This is an introductory level textbook which explains the elements of high temperature and high-speed gas dynamics. Readers will gain an understanding on how the thermodynamic and transport properties of high temperature gas are determined from a microscopic viewpoint of the molecular gas dynamics, and how such properties affect the flow features, the shock waves and the nozzle flows, from a macroscopic viewpoint. In addition, the experimental facilities for the study on the high enthalpy flows are described in a concise and easy-to-understand style. Practical examples are given throughout emphasizing the application of the theory discussed. Each chapter ends with exercises/problems and solutions to enhance the learning experience. Written in a clear and easy to follow style, the author covers all the latest developments in the field including basic thermodynamic principles, compressible flow regimes and waves propagation in one volume Covers theoretical modelling of High Enthalpy Flows, with particular focus on problems in internal and external gas-dynamic flows, of interest in the fields of rockets propulsion and hypersonic aerodynamics High enthalpy gas dynamics is a compulsory course for aerospace engineering students and this book is a result of over 25 years' of teaching by the author Accompanying website includes a Solutions Manual for exercises listed at the end of each chapter, plus lecture slides High Enthalpy Gas Dynamics is designed for graduate students in mechanical engineering, aerospace and applied physics courses, as well as designers and engineers working in the field of re-entry gas dynamics. Zusammenfassung This is an introductory level textbook which explains the elements of high temperature and high-speed gas dynamics.
